Preface Water main breaks are a primary cause of lost revenue and service for all water providers. Some water leaks make the evening news or the front page of the local newspaper. Others may go undetected until an unrelated excavation uncovers them or a mysterious soggy spot is...
Overview Various forms of chlorine are commonly used in drinking water and reuse applications for their ability to disinfect and maintain a residual level of disinfectant throughout the distribution system. The majority of utilities in the United States use chlorine gas during...
This video covers the types of disinfectants used in water treatment, how disinfection by-products form and strategies to control DBPs including guidelines set by the USEPA through the Stage 1 and Stage 2 Disinfectants and Disinfection By-products Rules.
Introduction Tertiary Butyl Alcohol (TBA) has multiple industrial and chemical uses. TBA is used in the manufacture of perfumes and cosmetics, as an additive in gasoline to improve the oxygen content, and is a metabolite of the fuel oxygenate, methyl-tert-butyleth
1.1 This guide covers general considerations for the use of test kits for quantitative determination of analytes in water and wastewater. Test kits are available from various manufacturers for the determination of a wide variety of analytes in drinking water, surface or ground...
